Did you know?
WebThe ionosphere reflects vertically incident signals below the critical frequency. The time-of-flight of the go plus return signal indicates how high the ionospheric layer is. Additionally the ionosphere layer may have a vertical velocity (either upwards or downwards) that induces Doppler shift onto the reflected signal.
